This invention relates to improvements in electrie razors, the general object of the invention being to provide means for actuating the movable cutting member from the motor so as to produce a rapid combined reciprocatorjy` and partially rotary motion of such member.

The invention also consists in certain other features of construction, combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and speciiically pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a longitudinal sectional View through the razor.

Figure 2 is a section on line 2 2 or" Figure 1.

Figure 3 is a plan view of the stationary cutting member.

Figure 4 is a similar view of the movable member.

Figure 5 is a section on line 5 5 of Figure 1.

In this drawing, the numeral I indicates the sectional handle or body which has attached thereto the cylinder-like housing 2 having the slots 3 therein and the movable member i is carried by said housing and is formed with the slots 5 which cooperate with the slots 3 in producing the cutting action, as will be understood. A motor 6 is located in a chamber in the handle and the conductors for which enter the end of the handle through the bushing An eccentric 8 is rotated by the motor and a pitman 9 has one end connected with the eccentric. The outer end of the pitman 9 is provided with a head I0 having a diagonally disposed slot II therein to receive the inner end of a stationary pin I2 carried by the handle to cause said end of the pitman to oscillate as it is reciprocated by the eccentric 8 of the motor. Rigidly secured to the pitman inwardly of the aforesaid slot II is a pin I3 which extends through enlarged slots I4 and I5 in the handle I and housing 2 respectively with its outer end seated in a socket i6 in the member 4. Through the instrumentality of the aforesaid assemblage of elements, the member 4 will be simultaneously oscillated and reciprocated as the pitman is actuated by the eccentric of the motor and thereby produces a shearing action between the diagonal walls of the slots 3 and 5.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction, combination and arrangement of the several parts, provided such changes fall Within the scope of the appended claim.

What I claim and desire to protect by Letters Patent is:

In an electric razor, a hollow handle, a toothed cylindrical housing carried by the forward end of said handle, a toothed cylindrical cutter member mounted in the housing for oscillatory and reciprocatory movements therein, a motor mounted in the rear portion of said handle, a pitman extending forwardly in the hollow handle from the motor and actuated thereby, a head on the forward end of the pitman having a diagonal guide slot therein, a pin passing through said guide slot and fixed in said handle, said cutter member having a, pin end receiving recess therein, and a second pin Xed on said pitman and having an end tted in said recess.
